  • Patent number: 7692217
    Abstract: One embodiment of the invention relates to an integrated circuit. The integrated circuit includes a first matched transistor comprising: a first source region, a first drain region formed within a first drain well extension, and a first gate electrode having lateral edges about which the first source region and first drain region are laterally disposed. The integrated circuit also includes a second matched transistor comprising: a second source region, a second drain region formed within a second drain well extension, and a second gate electrode having lateral edges about which the second source region and second drain region are laterally disposed. Analog circuitry is associated with the first and second matched transistors, which analog circuitry utilizes a matching characteristic of the first and second matched transistors to facilitate analog functionality. Other devices, methods, and systems are also disclosed.

  • Publication number: 20030124821
    Abstract: Disclosed are apparatus and methods for forming abrupt junctions in semiconductor devices. Initially, a substrate (200) is implanted with an amorphizing element (208) in a desired area (300), rendering the melting point of the desired area lower than the melting point of the substrate surrounding the desired area. A desired dopant (302) is implanted into the desired area, and the desired area is then annealed by an energy source (402, 506) such that only the desired area melts, allowing the dopant to diffuse throughout only the desired area.
